I am having the same problem and am getting pretty discouraged. I just sent an email from my home email but both my home and work email contain my username so hopefully you can match it up with my account.
I purchased the php data exporter a couple of weeks back... after some trouble got it working. Then I think last weekend(?) I purchased the file upload php scripts and now my exporter no longer works. My client is losing patience in waiting for something that I expected to be able to deliver quickly and easily.
